GLASS PARTICLE FOR SOFT MAGNETIC COMPOSITE MATERIAL, AND METHOD FOR PRODUCING SOFT MAGNETIC COMPOSITE MATERIAL

摘要

Provided is a glass particle from which a soft magnetic composite material having small eddy current loss and high strength can be produced. A glass particle for a soft magnetic composite material comprises, for example, a crystallized glass that contains, in mass%, SiO₂ and B₂O₃ in the total amount of 10% or more, B₂O₃ in an amount of 25% or less and ZnO in an amount of 40 to 65% in terms of oxide contents, and has an average particle diameter of 1 to 500 nm.
